Improvement in looms



UNITED STATES PATENT OFFICE.

WILLIAM BREITENSTEIN, OE NEW YORK, N. Y., ASSIGNOP TO M. FISCIIEL & CO., OF SAME PLACE.

IMPROVEMENT IN LOOMS.

Specification forming part of Letters Patent No. 38,195, dated April 14, 1863.

T 0 all whom it may concern:

Be it known that I, WILLIAM BEEITEN- STEIN, of the city, county, and State of New York, have invented a new and useful Improvement in looms for weaving corsets and for weaving other irregular goods; and I do hereby declare that the following is a full and exact description of the same, reference being had to the annexed drawings, which form a part of this specification.

Figure l is a cross-section through the takeup roller and through the novel portions of my loom. Fig. 2 is a rear view of the same parts, or of a portion of them.

Similarletters of reference indicate like parts in both the figures.

My invention is an improved means of operatin g a divided take-up for irregular weaving. I have found by experiment that the f Ibric cannot so easily and certainly be woven of a uniform texture by other means.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation by the aid of the drawings and of the letters of ref- (rence maiked thereon.

A is the frame of the loom, and F is the irregular fabric which is being woven.

K K, Src., are the several sections of a divided take-up roller, which are mounted side by side upon a fixed shaft or cylindrical bar, L, so as to turn easily thereon, either altogether alike, so as to produce the effect of an o dinary take-up, or some faster than others, as may be required. This divided or sectional take-up roller is the subject of another and separate application for patent by me. and will be here described only in brief. Each section is adapted to act independently of the other sections, so that when required it may turn while its neighboring sections remain at rest, and vice versa. Each section has a part of its surface adapted to act properly upon the fabric, as at 7c, and another part properly toothed, so as to mesh into and be driven by another wheel, as at K. The surface la is nely iiuted longitudinally, as represented,and the cloth is forcibly pressed thereon by corresponding rollers or Wheels mounted in springs above, as represented, there being one pressure-wheel and one spring to perform this duty upon one wheel or section of the divided takeup roller, and a separate pressurewheel ard spring for each other wheel or section of the divided take-up roller. Aseparate gear-wheel, K', meshes into the toothed portion K of each section of the divided takeup roller. The several wheels K' are all mounted loosely on a fixed shaft or cylindrical bar, L, so that each may turn independently of those by its side. A separate gearlwheel, K3, meshes into each wheel K. A larger gearLwheel, K3, is cast on the' side of each gear-wheel K2, and the turning of the wheel K3 thus necessarily turns the several wheels K2 K and K k. The wheels K2 K3 are (like the others) mounted loosely on a fixed shaft, L2, and the several sections of the divided-take-up are by reason of this construction of the mechanism capable ot' being separately operated, each having a motion corresponding to that of its corresponding wheel, K3, but slower. Each separate wheel K3 is caused to turn to a proper extent at the proper time by means of a separate lever and ratchet under the control of what is known as the Jacquard mechanism. The general character of the jacquard is well known to all who are familiar with complicated weaving and need not be described.

In weaving corsets and other irregular articles by power-looms the jacquard is ernployed to properly operate the warp-yarns so as to weave the gores. In order to adapt such to my invention it is necessary simply to add to the jacquard additional mechanism of a like character, so as to operate other strings than those which control the warp, and to connect such other or additional strings to the takeup mechanism in the manner now to be described.

U represents one of such additional strings lea-din g down from the jacquard and subject,

like the other strings, to be pulled and ret leased at short intervals, or to be allowed to rest for a long period, according as holes are punched in the cards of the jacquard to control it.

V is a lever mounted loosely on the shaft or roundbar L2, so that it may turn freely thereon.

X is a ratchet mounted on the lever V and pressed against the teeth of the large wheel K3 by the spring So long as the string U is allowed by the jacquard to remain unpulled the wheel K3, and consequently the corresponding section of the divided take-up, remains stationary, allowing the adjacent'scctions of the take-up to turn or not accordingly as they are respectively actuated by their several connections under the control also ofthe jacquard but the moment the string U is pulled and released the levei Vcorrespondingly reciprocates, and by the aid of the ratchet X turns the wheel K3, and its section oi' the take-up. The pawl J, mounted on a fixed shaft or bar below, allows the motion ofthe take-up in one direction only in the'obvious manner, and there being separate pawls foreach section of the take-up roller, connected in the man ner shown, it follows that the action of each part of the divided take-up is complete in itself' and entirely independent of the other parts of the s :me takenp, exceptas they are all connected t) and controlled by one and the same set of Jacquard mechanism.

ljdo not esteem the precise form or number of the parts to be essential to the success of -my invention. `I can employ a greater or a smaller number of wheels K K2, Snc., and can vary the `size and arrangement indefinitely;

- but I .prefer to employ such a train of mechan mingle with or stand near the strings which actuate the warp. I prefer to employ levers V of such length that the ends to which the strings are attached will Work freely below and without contact with the lay or batten.

The general arrangement of parts represented will operate with success, and it is easy for any skillful mechanic to nd the proper reduction of motion to enable the vibrations of the strings U to induce a just sufficient amount of motion in the corresponding part of the takeup, so that the fabric will be closely and properly woven in every part.

The advantage due to my invention lies in the uniformity and certainty of the action of each section at the proper time.

Having now fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

Operating or controlling the operation of a divided take-up by Jacquard mechanism, so that the action of the several sections of the take-up shall. be determined thereby, for the purpose herein set forth.
